Product Description

Invenio is the first and single revolutionary step taken towards turning a dream into reality in the metal detector industry. It represents one of the most dramatic advances in metal detection technology since conventional metal detectors first appeared on the market in the 1930s.

While many new features and improvements have been introduced over the decades, Invenio provides the first major leap in meeting real user expectations: deeper target detection, target type understanding, true depth reading, target shape display, dimension estimation and the ability to detect underground anomalies and cavities.

After years of extensive research, development and advanced engineering studies, Nokta has developed the world’s first Smart Detector & Imaging System β€” the Invenio Pro. It is built on exclusive Nokta technology and advanced imaging know-how backed by multiple patent applications.

Key Features

  • Artificial Intelligence: Artificial neural network technology helps the device provide superior shape extraction and depth indication through adaptive learning algorithms.
  • Multi-Purpose Detection: Detect deep treasures, caches, coins, relics, ground anomalies, underground caves and tunnels.
  • High Performance & Unmatched Depth: Locate deep targets that many traditional detectors fail to detect.
  • 3 Non-Motion Search Modes: Basic / Expert / Ground Anomaly & Cavity.
  • 3 Motion Search Modes: All Metal / Fast / Deep.
  • 17 Languages: Multilingual interface for users worldwide.
  • Online Firmware Updates: Keep your system updated via USB on PC.
  • 2.4GHz Wireless Connection: Wireless communication between system box and shaft, plus optional wireless headphones support.
  • Vibration: Target vibration feedback for hearing impaired users and noisy environments.
  • Excellent Discrimination & Unmasking: Save time by focusing on wanted targets and avoiding unnecessary digging.
  • Fast Recovery Speed: Find valuable targets hidden among trash and iron.
  • LED Flashlight & Screen Backlight: Detect comfortably in low-light or night conditions.
  • Archive Function: Save 3D graphs and screenshots and transfer them to your PC.

Ideal For

  • Deep treasure hunting
  • Cache and relic searching
  • Underground cavity and tunnel detection
  • Advanced users who need visual target analysis

Detection Systems & Modes

The Invenio Pro combines smart imaging, artificial intelligence and advanced VLF detection into a powerful system designed for deep target analysis and underground structure detection.

Artificial Intelligence

Adaptive learning algorithms and neural network technology improve target shape extraction and depth indication for more advanced underground analysis.

3D Imaging & Cavity Detection

Identify underground anomalies, cavities, tunnels and large buried objects with visual graphing and advanced ground analysis.

Multi-Mode Search System

Use three non-motion modes and three motion modes depending on whether you are analyzing cavities, deep treasure, or conventional metal targets.
